The voice of Natsumi Tsujimoto (辻本 夏実, Tsujimoto Natsumi) was provided by Sakiko Tamagawa and her English voice by Tamara Burnham Mercer. In the live action version, she was portrayed by actress Misaki Ito.

Natsumi is an officer stationed at the fictional Bokuto Station in Tokyo's Sumida Ward. She is very outgoing as well as very laid back. She often demonstrates superhuman strength second only to Shoji Tokairin and is a motorcycle enthusiast, capable of high-risk maneuvers on both bikes and mopeds. Natsumi has a prodigious appetite for food and alcohol, and has been known to show up at work with a hangover. She is also a chronic late sleeper. Despite having many bad habits, she is a very capable police officer and does her job seriously when needed. She keeps a mini-moped, a Honda Motocompo (JR-2) in Miyuki's Honda Today squad car and uses it when a flanking strategy is required. It is prominently labeled "NATSUMI" (in the Nihon-shiki transliteration system) before her first day at Bokuto in the beginning of the first anime, later re-coloured and re-labeled "POLICE" in the later appearances and on the Bandai Model kit of the Honda Today. When off-duty, she operates a Yamaha RZV motorbike until it is damaged beyond repair during later part of the first season. She is subsequently tricked into buying a Subaru R-2, which is in a near-non-functioning state. This car is then thoroughly renovated and heavily modified by Miyuki into a patrol car. She uses the wrecked motorbike's engine, modifying the car to make its operation follow closely to that of a motorbike. In the manga version, this car operates with double engines.

Natsumi is also familiar with judo and kendo, being able to defeat her opponents during training sessions. Her strength and her familiarity with hand-to-hand combat complement Miyuki's brilliant mind in creating devices or modifying known vehicles very well, making her and Miyuki famous throughout Bokuto Station. She is also the only person in this series able to consistently defeat Strikeman's fastballs and is called Home-Run Girl by Strikeman for this very reason.

According to the information in the You're Under Arrest series, Natsumi was born on August 12, 1975. Not much information is revealed in the story, though she had lived in Asakusa before enrolling in the Metropolitan Police Department Academy and became classmates with Miyuki Kobayakawa before being dispatched elsewhere in the Greater Tokyo Area.^[2]

The two eventually met by accident when Natsumi was late for work during her first day on duty with the Bokuto Station. She was partnered with Miyuki for a number of years. But for a short time, Natsumi was scouted by Tokyo Metropolitan Police Department Headquarters to be part of a prototype female motorbike unit before declining an invitation to train further with them.^[3] She was known to be infatuated with Detective Tokuno and the Kachou of the Traffic Division before meeting Shoji Tokairin, who became her rival and love interest.^[4] Natsumi and Miyuki, later on in the series, broke the back of a car smuggling syndicate that operated by stealing luxury vehicles, leading to the group's disbanding. Due to her actions, Assistant Kaoruko Kinoshita moved her to the Tokyo Metropolitan Police Department with Miyuki as part of her specialized training program in enhancing officer's skills related to police work.^[5] During the Hachi-Ichi-Go crisis (Bee Number One in the dub of You're Under Arrest: The Movie), she and Miyuki proved themselves as law enforcers when they apprehended renegade police officer Tadashi Emoto as he tried to commit suicide by trying to jump from the top floors of the Tokyo Tower. She was also sent to Los Angeles in the United States with Miyuki as part of a foreign officer exchange program with the Los Angeles Police Department.^[6]

At the end of the series, Natsumi is recruited to serve in the Special Assault Team and was an operative stationed with the Tokyo Metropolitan Police Department branch. Her partnership with Miyuki and subsequent transfer to the Special Assault Team had then ended nearly on bad terms, almost destroying their friendship until coming to terms with reality.^[7] She was replaced in Bokuto Station by Saori Saga, an ex-student who she and Miyuki saved during her police officer days before Saori was dispatched to the said station.^[8]

She had been temporarily been at Bokuto again^[9] before being transferred out to be trained under the JGSDF's Ranger Platoon before being reassigned again to Bokuto Station, serving as Miyuki's partner again after Saori had left Bokuto to be relocated in another station.^[10]

A character that is parodied after Natsumi is shown in the first episode of Full Metal Panic? Fumoffu. She is depicted as a wild policewoman who chases the two main character in a police car. Though, in YUA, Miyuki is the car driver of the duo, not Natsumi.

In-universe information
Occupation	Tokyo Metropolitan Police Department officer
Home	Okayama Prefecture
Nationality	Japanese

The voice of Miyuki Kobayakawa (小早川 美幸, Kobayakawa Miyuki) was provided by Akiko Hiramatsu (Japanese), and Jo Ann Luzzatto (English; OVA) & Juliet Cesario (English; onward) (Filipino) Kathyin Masilungan. In the live action version, she was portrayed by actress Sachie Hara.

Miyuki is Natsumi's partner and roommate. Miyuki is not as physically challenging as Natsumi, but she is much more thoughtful and more polite. A technical genius, Miyuki frequently performs custom vehicle modifications for various people at the precinct and is an expert with computers. Miyuki is a superb driver, almost as daring as Natsumi, and very difficult to shake in a pursuit. She is also punctual, shy, and diligent – in contrast, Natsumi is tardy, bold, and frequently lazy. Her mini patrol car, a Honda Today, is a heavily modified version for patrol duties. Starting with Today's 545 cc EH engine, Miyuki has stroked it out to 600 cc and turbocharged as well as converted to DOHC. Later she swaps the engine to a 700 cc stroked version of the later 656 cc MTREC engine (although still having a yellow number plate for K-cars), also with twin cams, a turbocharger, an intercooler, and nitrous oxide boost. She also has a blue Toyota Sports 800 as her car.

Unlike Natsumi's infatuation towards the chief (Kachou) of Traffic Division, Miyuki admires and respects him because of his dedication in working with the division. During situations where force was the only solution, Miyuki uses airsoft guns with paintball bullets in order to incapacitate or to leave a homing beacon on the opponents. Her love interest happens to be with the "White Hawk" Ken Nakajima but has initial difficulty in telling him until the end of the series.^[11] Her feelings for Ken were driven to the point when she pointed an air gun on Natsumi's head when she joked that she would have to marry Ken in the future.^[12]

Miyuki is fearful of anything that cannot be explained by science, such as the paranormal, supernatural or anything that was similar to science fiction. She is also afraid of reptiles.^[13]

Her character design was also used as the template for a goddess whom the characters prayed to in a four panel gag strip added to a version of YUA who eventually became Belldandy when the strip proved popular and was developed into Oh! My Goddess.^[14]

According to the information in the You're Under Arrest series, Miyuki was born on April 7, 1976. She had previously lived in the Okayama Prefecture before moving to the Greater Tokyo Area and entered the Metropolitan Police Department Academy and was classmates with Natsumi Tsujimoto before being transferred to Bokuto Station. She resides currently in Kōtō, Tokyo alongside Natsumi.^[15]

When she was trying to pick up Natsumi, she met with her instead by luck when seeing her breaking some of traffic violation rules (to the point that her driving license can be suspended) but she knew at once that she's Natsumi, her partner to be. Eventually catching up with her, Miyuki made a first impression with her and after Natsumi's transfer to Bokuto Station was complete, Miyuki and Natsumi became partners in the station's Traffic Division. The two became famous with Miyuki's brains and Natsumi's fists in solving various cases involving either themselves or with their colleagues. Miyuki was the other half of the duo responsible for ground breaking work in dismantling a mysterious car smuggling syndicate operation in Tokyo, resulting in her subsequent transfer to the Tokyo Metropolitan Police Department's Criminal Investigation Bureau^[16] under its Scientific Investigations Laboratory. The Lab invited her to permanently transfer to the department, but she refused the offer.

In the Hachi-Ichi-Go (蜂一号) crisis (Bee Number One in the dub of You're Under Arrest: The Movie), Miyuki's expertise in computers and in electronics have managed to gain breakwork during initial investigations over the mysterious power outages in the Sumida Ward, but was not able to secure any details regarding them. Nearing the end of the movie, she and Natsumi apprehend renegade officer Tadashi Emoto after wounding Kachou as a means of "proving" that he acted alone throughout the crisis. Miyuki was sent to Los Angeles with Natsumi as part of a foreign police officer exchange program for a short time with the Los Angeles Police Department.^[6]

Nearing the end of the series, Miyuki nearly broke her friendship with Natsumi after learning that the latter was being recruited into the Special Assault Team. The two patched up their differences when Miyuki told Natsumi that she wasn't open enough for her to accept Natsumi's recruitment into the SAT^[17] since the two had acted like real friends, even like sisters when Miyuki explained that Natsumi's SAT recruitment happened so fast without her realizing it all along, which forced her to shield herself from seeing reality as it was.^[18] Miyuki also renewed her "friendship" with Nakajima, further opening their relationship to other possibilities.^[11]

Her partner is Saori Saga, who took over Natsumi's position after she was permanently stationed in the Tokyo Metropolitan Police Department branch as part of her duties as an SAT operative^[8] before being transferred to the United States to conduct forensic training.^[10]

Miyuki was among the Top 10 Most Popular Female Characters in the August 2001 issue of Newtype magazine.^[19]

Voiced by: Bin Shimada (Japanese); Marc Matney (English) Ken Nakajima (中嶋 剣, Nakajima Ken) is a motorcycle patrol officer stationed in Bokuto Precinct who is such a gifted rider that he might have a successful racing career if he wanted it. Ken is strong, tough and handsome but at the same time, was terribly shy. He and Miyuki share strong feelings for each other, but have difficulties expressing them. He is the only son of Daimaru Nakajima (who manages a motorbike shop called ZAPPER) and the stepson of his teenaged stepmom Sena Wakabayashi. Details on his mother were not revealed, but it is known that his father became a widower before the OVA and first season series started.^[20] His peers call him "White Hawk" for his skills as a motorbike officer in chasing down various offenders. His family was from the Mie Prefecture.

Ken, through the anime and live action versions, uses various motorbikes in and out of police work. He uses a Suzuki GSX-R750 fitted with sirens and horns meant for police use in the TV series and a Kawasaki ZX-9R in the movie . He used a Kawasaki KLE-500 when he tried to chase down a high-speeding offender in the OVA. When off-duty, he uses a Yamaha V-Max. The only exception is in the drama version when Ken is seen using a Honda motorbike.

He is portrayed in the live action by actor Kazushige Nagashima.

She is an incorrigible gossip who pokes her nose into everything that happens at the precinct. Unfortunately, she frequently misinterprets things she sees and hears about, resulting in embarrassment and complications. She keeps an especially close eye on Miyuki and Ken. Yoriko also enjoys heckling her colleagues, especially when she talks about anything supernatural or paranormal.

She is also clumsy in anything she does but always can somehow cover the trouble created with her luck, which made her the top in class during her years in the Metropolitan Police Department Academy and earned the ire of her classmate Chie Sagamiono, who had aspired to become valedictorian back in their academy days.^[21] She is also insecure about her job for a short period of time when she saved an elementary student from Yakuza thugs. ^[22]

She is portrayed in the live action by actress Otoha.

After reforming herself, Saori graduated from high school and studied in the Metropolitan Police Department Academy since she admired Natsumi and Miyuki for their hard work in the force and was assigned to Bokuto Station's Traffic Division. On her first day, she got into trouble with them after trying to make a big impression by making the Traffic Division office neat (unwittingly getting rid of many personal belongings from others while she is at it). In the first few days of work, she scorned her colleagues and superior for being lax in their duties in the office and constantly reminds them of their responsibilities as police officers,^[24] even though Natsumi and Miyuki advised her to relax a bit since she was taking police work too personal.^[25] As time went on, Saori had learned to accept them and became fast friends with her Bokuto station co-workers, especially with Natsumi and Miyuki.

When she noticed that Miyuki wanted to break up her partnership with Natsumi, Saori was the only persistent one in convincing her to amend their ties since she couldn't bear to see her get depressed over Natsumi's supposed selection into the Special Assault Team. She is Miyuki's new partner before being transferred to a different station.,^[10] which was Johoku Station as a cyber crimes division officer.^[26]

Kachou (花蝶, Kachō, lit. "flower butterfly") is the head of the Bokuto Station's Traffic Control Department. His name is pronounced the same as the "chief" (課長, kachō) position he holds, but the spelling is revealed in second season by his monk uncle (a.k.a. Fox). He is a stern, but fair leader who uses a relaxed touch to keep his team of misfit officers in line. Natsumi had a long-standing crush on him before she met Toukairin.^[27] Though he allows his subordinates to do as they normally please in the station, he reminds them of their priorities as police officers.

In the movie, he got in trouble with Superintendent Arizuka when he was linked to Emoto, who was suspected of starting the Hachi-Ichi-Go (Bee Number 1) crisis in the Greater Tokyo Area. First stripped off his command and thrown into a cell by Arizuka due to suspicion of coercing with Emoto, he eventually disclosed details regarding both Emoto and Project "Hachi-Ichi-Go", as well as the fact that Emoto severed connections with him as well. During the final confrontation in Tokyo Tower, Emoto shot him in the leg, reinforcing the fact that he was not Emoto's accomplice.

He uses a Honda NSX as his personal car when doing police work in the OVA. In the rest of the series, He uses a Honda Legend.

Takao Arizuka (蟻塚 貴男, Arizuka Takao) is a superintendent from the Tokyo Metropolitan Police Department with the rank of Superintendent; he is feared by low-ranking officers since his mere presence in a police station during inspection would mean the end of someone's career as he always bring a notebook with him.^[28] However, in reality, he is lenient and willing to make arrangements (even if he has to make personal sacrifices to make such an arrangement possible as is) to accommodate the need of his subordinates so long as they get the job done in the end. On the other hand, Arizuka is strict and always reminds his subordinates to follow the guidelines set by their superiors while doing their best according to their capabilities. For this, Yoriko dubbed Arizuka as the king of Hades.^[29]

In the movie, Arizuka realized that he, as a Superintendent, knew less about the disappearance of Tadashi Emoto as well as the Hachi-Ichi-Go paper that Emoto made for the Tokyo Metropolitan Police Department than the Chief of the Bokuto Precinct Traffic Division and temporarily stripped Kachou off his rank and command when the latter refused to provide details regarding them.

A costumed vigilante who calls himself a superhero, Strikeman (ストライク男, Sutoraiku Otoko) uses baseballs and related items to punish offenders such as public drunks, flashers, and parking violators. He has come to the attention of Bokuto Precinct on several occasions, earning notoriety as a major nuisance and complete loon. He seems to have a fixation on Natsumi, considering her both his nemesis and his sidekick while referring to her as "Home-Run Woman." As of Full Throttle, there has been no clue so as to who the identity of Strikeman is. At one time during the 1st season, Nakajima was even suspected by his colleagues to be Strikeman, due to some events and a very similar appearance, but was found to be not the case.

Many attempts were placed to apprehend him, but Strikeman escapes due to the various fastball pitches that he uses as weapons. When he tries to enact "proper justice" on the offender's property such as their cars, Strikeman uses baseballs with sharp spikes on them and in fact, has used them against Miyuki and Saori as a means of distraction. He uses a Harley-Davidson Softail motorbike, designated FLSTF.^[41] He had recently returned after months of self-exile into the mountains to defeat Natsumi in another game of baseball.^[42]

50 C.C. Old Lady (原付おばさん, Gentuki Obasan) is an old woman who spends the majority of her time going after discounts and sale events. To the annoyance of every Traffic Division officer in the Bokuto Precinct, she does so relentlessly and is perfectly willing to commit any traffic violation in order to get to the sales location faster, having proven herself just as aggressive on the road as Natsumi or Nakajima (except that she does it all the time) and counting on the reflexes of people or vehicles she was about to collide with rather than her skills in operating a scooter to avoid accidents. However, another situation would intervene (such as repeating motorcycle thefts or bomb threats against a department store) whenever there's an attempt to apprehend her, allowing her to go off the hook. Her name was never revealed.

For transportation she uses a motor scooter (with a 50cc engine, hence her nickname), which tends to be overloaded with groceries and other merchandises that she purchased during discount events.

Most fans of the show have named her Scooter Lady and Scooter Mama as well.
